brother had been abducted by Ceallach he was roused to fury and he
followed Ceallach to Tara taking with him his foster child,
scil.:--Corc Duibhne, the son of Cairbre, son of Conaire, son of
Mogha Lamha whom Cormac held as a hostage from the Munstermen, and
whom he had given for safe custody to Oengus. When Oengus reached
Tara he beheld Ceallach sitting behind Cormac. He thrust his spear
at Ceallach and pierced him through from front to back. However as he
was withdrawing the spear the handle struck Cormac's eye and knocked
it out and then, striking the steward, killed him. He himself
(Oengus) with his foster child escaped safely. After a time Cormac,
grieving for the loss of his son, his eye and his steward at the
hands of Oengus of the poisonous javelin and of his kinsmen, ordered
their expulsion from their tribal territory, i.e. from the Decies of
Tara, and not alone from these, but from whole northern half of
Ireland. However, seven battles were fought in which tremendous loss
was inflicted on Cormac and his followers before Oengus and his
people, i.e. the three sons of Fiacha Suighde, namely, Ross and
Oengus and Eoghan, as we have already said, were eventually defeated,
and obliged to fly the country and to suffer exile. Consequent on
their banishment as above by the king of Ireland they sought
hospitality from the king of Munster, Oilill Olum, because Sadhbh,
daughter of Conn Ceadcathach was his wife. They got land from him,
scil.: the Decies of Munster, and it is to that race, i.e. the race
of Eoghan Mac Fiacha Suighde that the kings and country of the Decies
belong ever since.

2. Of this same race of Eoghan was the holy bishop Declan of whom I
shall speak later scil.: Declan son of Eirc, son of Trein, son of
Lughaidh, son of Miaich, son of Brian, son of Eoghan, son of Art
Corp, son of Moscorb, son of Mesgeadra, son of Measfore, son of Cuana
